Designed by Jaanus Osugaar, the spinning accelerometer chair lets you sit and spin to your heart's content. The chair uses six balls inside the base to keep the chair moving and hand straps to keep you from falling out. It's meant to be refreshing and energizing, but there's a good chance you may end up puking in mid-spin. That's assuming you can stomach the $1000 price tag. [Bouf via LikeCool]
